UNITED NATIONS, Sept. 10 (Xinhua) -- The UN envoy for Afghanistan on Tuesday voiced support for the relative Afghan parties to conduct a "credible and inclusive" presidential election slated for later this month.

Tadamichi Yamamoto, the special representative of the secretary general for Afghanistan, described the election as "another step in strengthening the foundation of a representative democratic political system" in the country.

The United Nations supports fully the efforts of independent election commission, and electoral complaints commission, security institutions, civil society as well as candidates, their supporters and voters to conduct credible and inclusive elections on schedule, he said.

The Sept. 28 poll will be the fourth presidential election in Afghanistan since 2001, when the United States invaded the country following the September 11 attacks and overthrew the Taliban, in power since 1996.

Yamamoto said many Afghan people hope for an end to the conflict, "but they also fear that peace might come at the sacrifice of freedom and rights, which the country has striven to protect and advance for the past 18 years."

Many young people, especially young women, are worried about future restrictions to their participation in the socio-economic and political life of their country, he added.

In this light, the UN envoy said credible elections would provide an important political foundation for the future of the country as well as legitimacy and authority to the elected president, which would be important in view of the expected peace process.

He pointed to Taliban's stated threat to disrupt the electoral process, stressing attacks directed against polling centers and civilians participating in the electoral process are unacceptable and urging the Taliban to retract the threat.

He also urged the government to provide adequate security arrangements to safeguard the electoral process and appealed to the Afghan people to exercise their right to vote.
